3.Finally we consider the case where the government's information is even more limited, as not only the linear taxes on trades but also the lump-sum tax cannot depend on the ex-post realization of the individual income shocks. In this case the second best cannot typically be attained, but we...

The explicit consideration of households also seeks to make a contribution to the emerging literature on dynamic optimal taxation with private information. One of the basic tenets of this approach is that normative analyses of government policies should consider constraints deriving from...

During the period 1990-93, Finland experienced the deepest economic downturn in an industrialized country since the 1930s. We argue that the collapse of the Finnish trade with the Soviet Union in and of itself resulted in a large contraction of the economy and a costly restructuring of the...

of imports and the degree of differentiation across inputs in a sector, for which I find strong support in the data. Moreover, imperfect competition establishes a link between FDI liberalization and optimal pricing: suppliers find optimal to reduce their prices in response to the possibility of...

framework, stochastic volatility in consumption growth generates both a state-dependent market price of model uncertainty and a stochastic market price of risk. We estimate the model using data from the bond and equity markets, as well as consumption data. We show that the model is consistent...

This paper incorporates a time-varying intensity of disasters in the Rietz-Barro hypothesis that risk premia result from the possibility of rare, large disasters. During a disaster, an asset's fundamental value falls by a time-varying amount. This in turn generates time-varying risk premia and...

In Bassetto with Sargent (2004) and Bassetto and Lepetyuk (2007), I developed a model that can be used to quantitatively assess the consequences of departures from Ricardian equivalence on the mix of public goods provided by the government. Those papers assume that mobility is exogenous and that...
